By compromising another operator’s spacecraft, or a hosted payload, an adversary can gain proximity, sensing, and relay capabilities that are costly to build from scratch and difficult to attribute. With control of an on-orbit asset, the actor may conduct local spectrum measurement and traffic analysis, attempt selective interference or spoofing at short range, or probe crosslinks and gateways where payload networks bridge to buses. In rideshare or hosted-payload contexts, weak segmentation and shared ground paths can provide insight into neighboring missions. More aggressive scenarios include remote proximity operations (RPO) to achieve advantageous geometry; however, physical grappling, docking, or exposure of debug/test interfaces is highly specialized and rare, with significant safety, legal, and tracking implications. Realistic attacker goals emphasize adjacency for RF leverage, covert relay, or data theft rather than mechanical capture.

| CM0009 | Threat Intelligence Program | A threat intelligence program helps an organization generate their own threat intelligence information and track trends to inform defensive priorities and mitigate risk. Leverage all-source intelligence services or commercial satellite imagery to identify and track adversary infrastructure development/acquisition. Countermeasures for this attack fall outside the scope of the mission in the majority of cases. | PM-16 PM-16(1) RA-10 RA-3 RA-3(2) RA-3(3) SA-3 SA-8 SI-4(24) SR-8 | A.5.7 A.5.7 6.1.2 8.2 9.3.2 A.8.8 A.5.7 A.5.2 A.5.8 A.8.25 A.8.31 A.8.27 A.8.28 | ||||
| CM0077 | Space Domain Awareness | The credibility and effectiveness of many other types of defenses are enabled or enhanced by the ability to quickly detect, characterize, and attribute attacks against space systems. Space domain awareness (SDA) includes identifying and tracking space objects, predicting where objects will be in the future, monitoring the space environment and space weather, and characterizing the capabilities of space objects and how they are being used. Exquisite SDA—information that is more timely, precise, and comprehensive than what is publicly available—can help distinguish between accidental and intentional actions in space. SDA systems include terrestrial-based optical, infrared, and radar systems as well as space-based sensors, such as the U.S. military’s Geosynchronous Space Situational Awareness Program (GSSAP) inspector satellites. Many nations have SDA systems with various levels of capability, and an increasing number of private companies (and amateur space trackers) are developing their own space surveillance systems, making the space environment more transparent to all users.* *https://csis-website-prod.s3.amazonaws.com/s3fs-public/publication/210225_Harrison_Defense_Space.pdf?N2KWelzCz3hE3AaUUptSGMprDtBlBSQG | CP-13 CP-2(3) CP-2(5) CP-2(7) PE-20 PE-6 PE-6(1) PE-6(2) PE-6(4) RA-6 SI-4(17) | A.5.29 A.7.4 A.8.16 A.7.4 A.7.4 A.5.10 | ||||
